Wind direction and speed at different altitudes, day/night.
Asked by: cessna186 5130 views General Aviation, Private Pilot, Student Pilot, Weather
I am going through questions for the EASA PPL theory exam and there are a few question about the weather which I don't know how to answer. For example this one:
It is midnight at an aerodrome in the center of England. The surface wind is 120/05 KT. What would the 2000 ft wind be? The answer is: 160/20 KT.
I know that winds move in the clockwise direction in the northern hemisphere, so obviously at 2000 it would be 120+, I assume the winds get stronger too, but how do you calculate the direction and speed precisely? I cannot seem to find any formula. Also, is important to know the time of the day?
Thanks!
